Sixth-grade mathematics enters the stage of mixed fractions and decimals, and the amount and complexity of calculations increase simultaneously, which is the key to Xiaosheng’s initial connection. This 100-question exercise covers scores plus or minus, and decimal scores are interchangeable, with answers for easy printing.
What is the difficulty of calculating in sixth grade? One is that fractions should be added and subtracted first, the other is that decimal and fractional mixing should be intermixed first, and the third is that the synthesis formula should pay attention to the order of operations at the same time. The three steps are stacked together, and all the wrong steps are wrong.
Key Approaches
- Fraction addition and subtraction: first find the common denominator, then calculate the fraction;
- Comparison of fractions and decimals: fractionalization into decimals or fractionalization into fractional reratios;
- Hybrid operation: strictly follow the “multiply and divide first, add and subtract after, bracket first calculate brackets”.
Practice Schedule
100 questions are divided into 5 pages, and one page (20 questions) is done every day for about 15 minutes. After completing the correction against the answer, revise the wrong question on the same day, and write the reason for the error clearly (is it a mistake? Or are the operations in the wrong order?).
Tips for parents
The calculation problem in the sixth grade is wrong. 90% is not careless, but unfamiliar with the method. Rather than letting the child brush the question repeatedly, it is better to accompany him to become proficient in single items such as total points, reduction points, and mutualization, and then to put on comprehensive questions. The number of questions in this exercise is sufficient to support the training process.
After passing the calculation, Xiao Shengchu’s mathematics had a foundation.
